Non-Lagrangian approach for coupled complex Ginzburg-Landau systems with higher order-dispersion
Roger Bertin Djob, Aurelien Kenfact-Jiotsa, A. Govindarajan
It is known that after a particular distance of evolution in fiber lasers, two (input) asymmetric soliton like pulses emerge as two (output) symmetric pulses having same and consta…
Nonlinear nonuniform -symmetric Bragg grating structures
S. Vignesh Raja, A. Govindarajan, A. Mahalingam +1
We explore the consequences of incorporating parity and time reversal () symmetries on the dynamics of nonreciprocal light propagation exhibited by a class of nonunif…
Multifaceted dynamics and gap solitons in -symmetric periodic structures
S. Vignesh Raja, A. Govindarajan, A. Mahalingam +1
We report the role of -symmetry in switching characteristics of a highly nonlinear fiber Bragg grating (FBG) with cubic-quintic-septic nonlinearities. We demonstrate…
Nonlinear anti-directional couplers with gain and loss
A. Govindarajan, Boris A. Malomed, M. Lakshmanan
Following the concept of -symmetric couplers, we propose a linearly coupled system of nonlinear waveguides, made of positive- and negative-index materials, which carr…
Cubic-quintic nonlinear Helmholtz equation: Modulational instability, chirped elliptic and solitary waves
K. Tamilselvan, T. Kanna, A. Govindarajan
We study the formation and propagation of chirped elliptic and solitary waves in cubic-quintic nonlinear Helmholtz (CQNLH) equation. This system describes nonparaxial pulse propaga…
